The best source for reliable, recent, and aggregate statistics about time useĀ for the US comes in the form of the American Time Use Survey. This data source, starting in 2003 and for every year thereafter, tallies the amount of time Americans spend in various activities, including travel by ten different purposes. Over the past decade, the amount of time spent in travel has declined six minutes: from 74.4 minutes to 68.4 minutes per day.
